New coil

[Anson]

I cleaned the points off and still nothing, so I think the coil is bad. I got it out last night and have a part number of 201781(IDA-9).

I tried ebay and Saturn surplus with no luck. Does anyone know where I can find a nos or replacement coil?

Thanks

Franks Surplus on E-Bay, VPW or Antelope Valley.

When you have the ignition on, do you get a spark if you put a screw driver on the points and anything else metal?

[Anson]

Not all the time. Sometimes I do, and it will start. Then it won't start, and there isn't any spark.

Be sure you're getting good voltage to the coil with the switch on as well. Check it with a voltmeter at the positive terminal.

Its an odd problem to be sure. I'm not sure I would agree that its the coil itself though. Granted, this one is built into the distributor, but its the general nature of small transformers like this to either work or not work. I'm thinking you have a bad wire somewhere ahead of it.

If it helps....

The wire that screws to the side of the ignitor housing, on the coil side, with the semi rounded cap runs directly to the on/off switch where it is attached in the upper right position as viewed from the front. There are 4 positions on the back the on/off switch, 2 rows of 2.
The wire number is 12.

So if you arent having trouble with any other systems...at least no known trouble, you can disconnect #12 at the on/off switch and at the ignitor hook up a continuity meter to both ends and wiggle the wire around and see if it loses continuity between the ends.

If the wire is bad somewhere splice it if you can...the end that attaches to the ignitor has an unusual end that I am not sure is available...I could be wrong on that though.


Battery power gets to the on/off switch via the cable to the foot starter switch that then runs toward the alternator. There is a splice between the foot starter switch and the alternator that branches off 5 wires...2 of these wires go directly to the on/off switch as wire #11...both of them are marked with 11. The #11 wires connect to the left side of the on/off switch as viewed from the front...one above the other.


I suppose it is possible that the on/off switch isnt getting power consistently due to a bad wire OR that the switch itself is bad...though I think a wire problem is much more likely here.
